Maybe the problem is in the dual system itself. Before the HMS era all attack rings were made as single part, making them durable enough to witstand the stress of the battle. HMS for the first time seperated AR into metal frame (that was in most cases durable enough to work on it's own) and plastic subframe that incorporated most of the desing elements. MFB system improved on that basic layout by increasing the metal content and making metal frames more detailed.
Dual layer system replaced metal with plastic and made whole thing a lot more prone to breakage. Connecting to thin layers of plastic is not as effective as making it a single piece in the first place. Connecting screws may add some strenght but underneath it all it's still two layers acting on their own. In most cases one layer brakes first. If they were glued it would be another story as laminated matterials act as "one", but when you have screws as connection points all the stess goues trough them at one point. I mean if HMS metal parts were braking (Dranzer MS had it's issues), plastic ones will break even easier.
After all this tops are meant to clash so making them durable should be their primary objective.
